Don't know about that.  There are still many scopes from 1970-1980's vintage
which still sell for at least $400 on ebay.  And these are
basically only entry level type scopes such as the Tek 764, 765 etc...

   For those that need a nice "new" digital and a

Also, not sure of the number, but at work, the idiot manufacturing test guys
purchased these new Tektronix scopes which are basically like the Tek
TDS3000 series except they are basically a pc running Windows Millenium.
These scopes in my opinion are absolute garbage.   They purchased about 5 of
them for about $12000 apiece and we have yet to even use them.  Of course,
they do come with typical nice windows screen savers!!!

All in all, for TC use, a simple old hitachi 15 MHZ, single channel tv
repairman scope is good enough.  These you can get on ebay for under $20.00
i think.
